Moroso 73827 Ultra 40 Race Sleeved Spark Plug Wire Set

The Moroso 73827 Ultra 40 Race Wire Set is a high-performance, sleeved spark plug wire set engineered for demanding race and street applications. Each wire is precision-cut to the correct length and factory-terminated at both ends with locking, corrosion-resistant steel terminals to ensure a reliable, low-resistance connection every time.

Key Features:

• Ultra 40 Race Wire construction — 40 ohms-per-foot spiral-wound core for superior EMI/RFI suppression without sacrificing spark energy
• Sleeved design — additional protective sleeve over the wire jacket for enhanced heat and abrasion resistance in tight engine bays
• High-temperature OEM-style silicone boots — bonded directly to the wire to create a moisture, fuel, and oil-resistant seal at each terminal end
• Locking corrosion-resistant steel terminals — factory crimped and terminated for a secure, positive connection at the distributor cap and spark plug
• Color-matched wire separators included (where applicable) — high-temperature plastic separators keep wires evenly spaced and away from heat sources
• Available in Blue and Red to complement your engine build

Moroso Ultra 40 Sleeved spark plug wires deliver consistent ignition performance for high-compression, forced-induction, and racing engines where reliable spark delivery is critical. Designed and assembled to exact OEM replacement dimensions, these wires install without modification.
